Recurrent nasal polyp and pansinus mucopyocele associated with bilateral blindness: a case report.

A 39 year old female with 24-month history of recurrent mucoid rhinorhea associated with progressive bilateral nasal blockage, headache, anosmia and bilateral impaired vision is reported. There was a past history of sinus surgery. The neuro-ophthalmic examination revealed left non-axial proptosis and visual acuity of nil light perception in both eyes at 3 meters. CT scan of the paranasal sinuses and brain showed markedly expanded left frontal sinus with sclerotic walls and expanded mixed density lesion in all the sinuses. She had surgery via trans-nasal, external and skull base approaches for effective clearance of the polypoidal masses and drainage of the sinus mucopyocele. Histological examination confirmed chronic inflammatory polyp. She remains stable to date although visual impairment and anosmia remained persistent. Patients with nasal polyposis require frequent follow-up even after surgical treatment for the early detection and management of complications to avoid consequences such as visual loss.
